Particularly the type of things big companies who move slowly do best.
You may find that unreasonable, but I believe this is a perspective that drives many poorly thought out regulatory laws which punish experimentation and companies which fail to execute with an (unreasonable) expectation of perfection. Another perspective is that these are growing pains of an immature company that many people took a (known) risk betting on, particularly people from a high-income bracket who could afford their early models.
Tesla should certainly be held responsible for their failures so they fix them - not fixing them would be what is unreasonable in my books.
There is a popular business concept called 'crossing the chasm' [1] that applies well here. Jumping from startup -> mainstream company is a significant leap which many companies fail to do. Tesla has not yet crossed this market gap and their ability to consistently provide support services such as these, rather than simply an innovative new product that people want, will likely be their primary challenge in the future.

Edit: I see you've made an edit on the subtext predicting downvotes from Tesla fanboys which I believe was the sentiment OP was referring to
I said that I (personally) will punish them financially by not buying their products until I can be sure they can provide the level of service that I require.
Tesla's ability to solve this problem will likely be their greatest challenge going forward. They've proven repeatedly that they can get their product and marketing right to get customers. But there's far more to a long-term large scale automobile company than that.
I believe the most rational perspective is trying to look at companies in the context of the development stage they are in. Tesla is a bit unique as they went public fast and made big promises, where they come off as a mature company... when they really aren't.
There's no way to phrase "wait 1+ month for needed, at times limiting, service on a $100,000+ vehicle" as being acceptable in any shape or form, not even "oh well, I guess you're just not an ideal early adopter". Especially as Tesla was claiming their disconnect from the dealership model was a good thing (which I agree upon).
